Preparation and Evaluation of Experiments

1. Theory of measurement of physical quantities: the reproducibility of the measurement results as the basis of the scientific method. Measurement as a process of comparison. Measuring units - SI system of units. Calibration and certification
2. Measurement uncertainty: the result of the measurement, the measurement error and the real value. The uncertainty of the measurement outcome. Statistical standard uncertainty (type A). Systematic standard uncertainty (type B). The combined standard uncertainty. Expanded uncertainty increases the reliability of measurement results. Covariance law and Gauss' law of propagation of uncertainty in indirect measurements. Functional dependencies – the band of confidence . Rules for rounding off and numerical formulation of the measurement result. Reliability and validity of measurement results.
3. Direct measurement parameters: a measurement of length, angle, volume, time, weight, temperature , pressure, electric voltage.
4. Scheme of the experiment: experimental design. General formats of graphs of physical dependencies. Realization of the experiment. The record of direct measurements - data table format. Evaluation and analysis of experimental results. Publication of the results of an experiment (necessary components of a laboratory report). Sample laboratory report.
